Hey rbf18270, :welcome: to the forum. :thumb:
When I first tried cutting cable TV, I looked seriously at the WA-2608, but the pros here cut that down right away. It's a Chinese antenna of a type with a terrible reputation. They advertise something like 125 mile range, which is ridiculous (65 miles is maximum in most locations, due to the curvature of the earth), and the rotors are very poorly made. They tend to break with any little wind, plus which the remotes are just silly -- there's no way to tell which way the antenna is pointing unless you can see it.
However, until they break those Chinese wonders should actually pull in good reception. There's a guy on YouTube who uses a similar model as an indoor antenna, which actually makes sense. Rotor less likely to fall apart indoors, and you can see which way the thing is pointed. However, I'm sure it looks ridiculous in the middle of the living room. :clown:
If you are using the WA-2608 outdoors, I would just plan on it breaking within a year. Might as well get something sturdier now, to avoid any down time. You probably do need an outdoor antenna, with that TV Fool Report.
I feel most people are better off without a rotor, and without any amplification if at all possible. Those two electrical parts are the first things to break in bad weather, plus a) amplification often does more harm than good, and b) turning the rotor constantly puts a crimp in the modern art of channel surfing. It's usually possible to eliminate the need for both devices. (E.g. I have a two antenna, two tuner setup that works fine.)
WBPX could have gone out for a day or two, or your WA-2608 might have rotated on its own a little, to the point a scan no longer picks it up. It's a 2 edge signal (it has to refract around two hills in your area) and it's a ways down in the chart, so it actually makes sense that station might flake in and out. Any little temperature inversion in the atmosphere can turn the 2 edge into a 3 edge -- which is basically hopeless.
A couple more questions for ya: Is the WA-2608 outside? Are there any major obstacles (trees or buildings?) blocking line-of sight to your main transmitters north-east and south-east? Do you use the rotator a lot? Are you splitting to more than one TV? I see you have it set at 20 feet. Any chance to get an outdoor antenna up higher, like 30 - 40 - 50 feet? Would you please list the stations you currently receive reliably (call letters, if possible)?
Reason I ask about the height: on the transmitter profiles, it looks like a little more height might get you line-of-sight over one of those hills. That could change the 2edge to 1edge, and improve stability tremendously. It might improve some other stations too, and maybe get you lower in the chart. You can test this out by trying greater heights on TV Fool.
Reason I ask for a station list, is I'm curious whether you are getting stations from one - two - or three different directions. If you don't care about WUNI (Spanish station), then it looks like you should get everything else in the green and yellow areas on your report. You only need a 39 degree beam width, which is pretty common. If you don't care about WNAC or WPRI (Fox and CBS are duplicated on other stations) then you don't need to worry about VHF, which would save a few bucks. So we need answers to these questions before recommending a specific antenna.
Best,
Rick
